Puncture fixation device

Abstract

This utility model discloses a puncture fixation device, relating to the field of medical device technology. It includes a puncture needle and a planar positioning component for adjusting and positioning the puncture needle in the X and Y directions. The mounting end of the planar positioning component is equipped with a puncture needle guide rail for angle control of the puncture needle. The puncture needle is slidably positioned within the puncture needle guide rail, and its relative position is positioned by hand-tightening a bolt. This utility model achieves precise multi-degree-of-freedom positioning of the puncture needle in the X / Y / Z axes and various angular directions through a three-dimensional sliding rail mechanism and a universal ball joint for combined adjustment.

This effectively solves the problem of the high difficulty of puncture surgery caused by uncontrollable factors such as reliance on the doctor's personal experience and direct hand operation.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a puncture fixation device. Background Technology

[0002] A biopsy is one of the more common clinical procedures. Through a biopsy, doctors can obtain tissue and cellular components from the lesion site. Combined with pathological examination, this allows them to accurately determine the location of the lesion and the severity of the patient's condition.

[0003] Currently, most biopsies performed in hospitals rely heavily on the doctor's personal experience. Based on MRI results, the doctor determines the approximate location of the lesion and directly performs the procedure with the needle in hand. During the procedure, hand tremors or inaccurate determination of the puncture path can inevitably lead to failure. To address this, we provide a biopsy fixation device. Utility Model Content

[0004] The purpose of this invention is to provide a puncture fixation device to solve the above-mentioned problems.

[0006] A further technical improvement of this utility model is that: the planar positioning component includes a Y-axis slide rail and a coil clamp slidably disposed on the Y-axis slide rail. A ball head slide rail that moves in the X-axis is slidably installed in the gap between the coil clamp and the Y-axis slide rail, and the ball head slide rail is fixed in the X and Y directions by tightening a hand-tightening bolt at the opening of the coil clamp.

[0007] A further technical improvement of this utility model is that: the end of the ball head slide rail away from the coil clamp is provided with a universal ball head, and is clamped by a ball head clamping structure, and the puncture needle guide rail is fixedly installed on the ball head clamping structure.

[0008] A further technical improvement of this utility model is that the ball head clamping structure includes two symmetrically arranged ball head clamps, the top of the two ball head clamps is provided with a clamping seat, the two ball head clamps are rotatably connected to the clamping seat, and a semi-circular groove is provided on the two opposite sides. The two cooperate to clamp the universal ball head, and the two ball head clamps can be tightened and fixed by hand-tightening bolts.

[0009] A further technical improvement of this utility model is that a MARKER plate is vertically fixedly installed on the top of the clamp at one side of the puncture needle guide rail.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention achieves precise multi-degree-of-freedom positioning of the puncture needle in the X / Y / Z axes and various angular directions through a three-dimensional slide rail mechanism and universal ball joint adjustment; the locking structure of the entire device is achieved by hand-tightening bolts, which can quickly lock the position and prevent displacement during the operation; it effectively solves the problem of the difficulty of puncture surgery caused by uncontrollable factors such as relying solely on the doctor's personal experience and direct hand operation.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Please see Figure 1-2 As shown, the puncture fixation device includes a Y-axis slide rail 1, a coil clamp 2 is slidably mounted on the Y-axis slide rail 1, the coil clamp 2 has a C-shaped structure, and a ball head slide rail 4 is provided between the coil clamp 2 and the Y-axis slide rail 1. The ball head slide rail 4 can reciprocate along the gap between the coil clamp 2 and the Y-axis slide rail in a direction perpendicular to the Y-axis.

[0018] The C-shaped structure of the coil clamp 2 is provided with a hand-tightening bolt 3 at the open end. The hand-tightening bolt 3 connects to both sides of the C-shaped opening of the coil clamp 2 and is tightened to determine the X and Y positions of the ball head slide rail 4.

[0019] A universal ball head is provided at the end of the ball head slide rail 4 away from the coil clamp 2. Two ball head clamps are symmetrically arranged on both sides of the universal ball head, labeled as ball head clamp one 5 and ball head clamp two 6 respectively. A clamp seat 7 is provided on the top of the two ball head clamps. The two ball head clamps are symmetrically rotated at the bottom of the clamp seat 7 by a pin 8. Semi-circular grooves are provided on the opposite side of the two ball head clamps. The two work together to clamp the universal ball head. The two ball head clamps are locked by a hand-tightened bolt two, thereby completing the clamping of the universal ball head.

[0020] A puncture needle guide rail 11 is fixedly installed on one side of the top of the clamp 7. A puncture needle 13 is slidably disposed inside the puncture needle guide rail 11. A hand-tightening bolt 12 is threadedly connected to one side of the puncture needle guide rail 11 to position and fix the puncture needle 13 relative to the puncture needle guide rail 11.

[0021] More specifically, a MARKER plate 10 is vertically fixed on the top of the clamp 7, located on one side of the puncture needle guide 11, so as to serve as a marker for image recognition and to be used to calculate the actual puncture trajectory in real time.

[0022] In use, this utility model uses the MARKER board 10 for software positioning. The software simulates the puncture surgery, puncture points and paths. The doctor adjusts each moving component according to the points and paths simulated by the software, and then tightens each bolt to fix the points and paths, and performs the puncture directly, thereby effectively avoiding the uncontrollable factors of hand operation.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
